怎么在springboot中集成hbase

依赖：

      org.springframework.data
      spring-data-hadoop-hbase
      2.5.0.RELEASE
    
 
    
      org.apache.hbase
      hbase-client
      1.1.2
    
 
    
      org.springframework.data
      spring-data-hadoop
      2.5.0.RELEASE
    

增加配置

官方提供的方式是通过xml方式，简单改写后如下：

@Configuration
public class HBaseConfiguration {
 
  @Value("${hbase.zookeeper.quorum}")
  private String zookeeperQuorum;
 
  @Value("${hbase.zookeeper.property.clientPort}")
  private String clientPort;
 
  @Value("${zookeeper.znode.parent}")
  private String znodeParent;
 
  @Bean
  public HbaseTemplate hbaseTemplate() {
    org.apache.hadoop.conf.Configuration conf = new org.apache.hadoop.conf.Configuration();
    conf.set("hbase.zookeeper.quorum", zookeeperQuorum);
    conf.set("hbase.zookeeper.property.clientPort", clientPort);
    conf.set("zookeeper.znode.parent", znodeParent);
    return new HbaseTemplate(conf);
  }
}

HbaseTemplate test :

@Service
@Slf4j
public class HBaseService {
 
 
  @Autowired
  private HbaseTemplate hbaseTemplate;
 
 
  public List getRowKeyAndColumn(String tableName, String startRowkey, String stopRowkey, String column, String qualifier) {
    FilterList filterList = new FilterList(FilterList.Operator.MUST_PASS_ALL);
    if (StringUtils.isNotBlank(column)) {
      log.debug("{}", column);
      filterList.addFilter(new FamilyFilter(CompareFilter.CompareOp.EQUAL, new BinaryComparator(Bytes.toBytes(column))));
    }
    if (StringUtils.isNotBlank(qualifier)) {
      log.debug("{}", qualifier);
      filterList.addFilter(new QualifierFilter(CompareFilter.CompareOp.EQUAL, new BinaryComparator(Bytes.toBytes(qualifier))));
    }
    Scan scan = new Scan();
    if (filterList.getFilters().size() > 0) {
      scan.setFilter(filterList);
    }
    scan.setStartRow(Bytes.toBytes(startRowkey));
    scan.setStopRow(Bytes.toBytes(stopRowkey));
 
    return hbaseTemplate.find(tableName, scan, (rowMapper, rowNum) -> rowMapper);
  }
 
  public List getListRowkeyData(String tableName, List rowKeys, String familyColumn, String column) {
    return rowKeys.stream().map(rk -> {
      if (StringUtils.isNotBlank(familyColumn)) {
        if (StringUtils.isNotBlank(column)) {
          return hbaseTemplate.get(tableName, rk, familyColumn, column, (rowMapper, rowNum) -> rowMapper);
        } else {
          return hbaseTemplate.get(tableName, rk, familyColumn, (rowMapper, rowNum) -> rowMapper);
        }
      }
      return hbaseTemplate.get(tableName, rk, (rowMapper, rowNum) -> rowMapper);
    }).collect(Collectors.toList());
  }
}
